HP's Meg Whitman slides off the list

HP's(HPQ) Meg Whitman ranked ninth on Glassdoor's tech CEO list last year, but she didn't even crack the overall top 50 in 2013.

The company has endured three multi-billion dollar writedowns during Whitman's tenure, which began in late 2011. Whitman also made the embarrassing admission in November 2012 that HP had been duped by an accounting scandal at its Autonomy software division.

Still, Whitman's approval rating fell just one percentage point over the past year to 79%. As other CEOs surged, she fell off the list entirely.

Without Whitman, no female CEO cracked the top 10 list for tech CEOs. In fact, only one woman made Glassdoor's top 50 list across all industries: Victoria's Secret's Sharen Turney clocked in at No. 42.
